Zoom Phone is the cloud-based business telephony offering from Zoom Communications, Inc., the public company best known for its Zoom Workplace collaboration suite. Launched in 2019, Zoom Phone extends Zoom beyond video meetings into full unified communications as a service (UCaaS), providing VoIP calling, SMS/MMS, and rich PBX capabilities in a single application on desktop, mobile, and desk phones.
Built natively on Zoom’s global cloud infrastructure, Zoom Phone is designed to replace legacy on-premises PBXs and fragmented phone systems with a modern, AI-powered service. It provides inbound and outbound calling over the public switched telephone network (PSTN), advanced call routing, auto attendants, call queues, voicemail with transcription, call recording, and tight integration with Zoom Meetings, Team Chat, Contact Center, and other Zoom Workplace components. Zoom emphasizes ease of administration via a centralized web portal and supports both native Zoom calling plans and bring-your-own-carrier (BYOC) options for enterprises.
The service has scaled rapidly: Zoom announced in October 2025 that Zoom Phone had surpassed 10 million seats globally, making it one of the fastest-growing cloud telephony platforms in the market. Adoption spans small businesses through large multinationals across industries such as technology, financial services, healthcare, education, and retail, reflecting demand for a single platform that can support voice, video, chat, and AI workflows for hybrid and remote teams.
Within the highly competitive dialer and VoIP landscape, Zoom Phone differentiates itself through its deep integration with the broader Zoom ecosystem and its AI Companion capabilities. Features like AI-generated call summaries, voicemail task extraction, and an AI-powered virtual receptionist, combined with a 99.999% uptime target and coverage in 40+ countries with optional BYOC, position Zoom Phone as a strong option for organizations that want to consolidate communications on Zoom while maintaining enterprise-grade reliability and compliance.
